Abstract (en)
[origin: WO2017093213A1] The invention relates to a method for creating a theoretical signature of a crystalline material sample, the theoretical signature corresponding to a curve of theoretical backscattered intensities as a function of acquisition geometries, characterised in that the method comprises the following steps: modelling (10) a three-dimensional atomic structure of the sample, the structure comprising at least one crystal lattice and being contained in a volume having a symmetry of rotation such that the distance between a centre of the structure and the atoms (24) arranged at the periphery of the structure is substantially constant; then, for each acquisition geometry: positioning (20) the structure according to the desired acquisition geometry by moving the spherical structure relative to the projection plane; calculating (30) the projection of the atoms (24) of the structure in the projection plane in order to obtain a projection image; estimating (40) the backscattered intensity from the projection image; and generating the theoretical signature from a plurality of estimated theoretical backscattered intensities.
